Abstract
A control system for vehicle power train components has an engine ECU, an AT ECU and a manager ECU. The manager ECU outputs command signals such as a target engine torque and a target AT range for the engine ECU and the AT ECU. The manager ECU retrieves data for completing a map for determining availability of the target engine torque from the engine ECU. The manager ECU checks the availability of a computed value of the target engine torque, and if it is necessary, the manager ECU replaces the target engine torque with an available value. The engine ECU executes an engine control process on the basis of the target engine torque of which availability has thus been ensured by the manager ECU. It is therefore possible to operate the vehicle power train components in a more appropriate manner.
